This section explains how to set jumpers for correct configuration of the main-
board.
Setting Jumpers
Use the mainboard jumpers to set system configuration options. Jumpers with
more than one pin are numbered. When setting the jumpers, ensure that the
jumper caps are placed on the correct pins.
The illustrations below show a 2-pin jumper.
When the jumper cap is placed on both pins,
the jumper is SHORT. If you remove the
jumper cap, or place the jumper cap on just
one pin, the jumper is OPEN.
This illustration shows a 3-pin
jumper. Pins 1 and 2 are SHORT.

Front Panel Connector
The front panel connector (FP1) provides a standard set of switch and LED
connectors commonly found on ATX or micro-ATX cases. Refer to the table
below for information:
FP1
Pin Signal Function Pin Signal Function
1 HD_LED_P Hard disk LED
(positive) 2 FP PWR/SLP MSG LED [dual color or single color (+)]

7 RST_SW_P Reset Switch 8 PWR_SW_N Power Switch
9 RSVD Reserved 10 NC No pin
Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indica-
tion that data is being read from or written to the hard drive. For the LED to
function properly, an IDE drive should be connected to the onboard IDE inter-
face. The LED will also show activity for devices connected to the SCSI (hard
drive activity LED) connector.
Power / Sleep / Message Waiting LED
Connecting pins 2 and 4 to a single- or dual-color, front panel mounted LED
provides power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pins 5 and 7 to a momen-
tary-contact switch that is normally open. When the switch is closed, the board
resets and runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a
momentary-contact switch that is normally open. The switch should maintain
contact for at least 50 ms to signal the power supply to switch on or off. The
time requirement is due to internal debounce circuitry. After receiving a power
on/off signal, at least two seconds elapses before the power supply recog-
nizes another on/off signal.

Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the mainboard or any of the surface-mount resistors
with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the mainboard, you may cause serious damage to the mainboard
or its components.
On most mainboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you can
clearly see the mainboard and processor socket.
Before installing the Processor
This mainboard automatically determines the CPU clock frequency and sys-
tem bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the mainboard, or changing the
settings in the system Setup Utility. We strongly recommend that you do not
overclock processors or other components to run faster than their rated speed.
Warning: Overclocking components can adversely affect the reliability of
the system and introduce errors into your system. Overclocking can per-
manently damage the mainboard by generating excess heat in
components that are run beyond the rated limits.
This mainboard has a Socket 462 processor socket. When choosing a proc-
essor, consider the performance requirements of the system. Performance is
based on the processor design, the clock speed and system bus frequency of
the processor, and the quantity of internal cache memory and external cache
memory.
The following processors are currently supported by this mainboard.
Athlon XP: up to 2600+, FSB: 266 MHz
Athlon: 650 MHz~1.4 GHz, FSB: 200 MHz, 266 MHz
Duron: 550 MHz~1.2GHz, FSB: 200 MHz
12

CPU Installation Procedure
The following illustration shows CPU installation components:
Note: The pin-1 corner is marked with an arrow
Follow these instructions to install the CPU:
1. Pull the CPU socket locking lever away from the socket to unhook it and raise the
locking lever to the upright position.
2. Match the corner on the CPU marked with an arrow with pin A-1 on the CPU socket
(the corner with the pinhole noticeably missing). Insert the processor into the
socket. Do not use force.
3. Swing the locking lever down and hook it under the latch on the edge of the socket.
4. Apply thermal grease to the top of the CPU.
5. Lower the CPU cooling fan/heatsink assembly onto the CPU
6. Secure the two retention clips on
either side of the fan/heatsink unit
onto the Socket 462 base.

7. Connect the CPU Cooling Fan
power cable connector to the
CPUFAN connector.
Notes: • To achieve better airflow rates and heat dissipation, we suggest that
you use a high quality fan with 4800 rpm at least.
• CPU fan and heatsink installation procedures may vary with the type of
CPU fan/heatsink supplied. The form and size of fan/heatsink may also
vary.
Installing Memory Modules
The mainboard has two 168-pin/184-pin DIMM sockets for SDRAM/DDR
(Double Data Rate) SDRAM system memory modules. The maximum memory
size is 1GB.
DDR SDRAM provides 800 MBps or 1 GBps data transfer depending on
whether the bus is 100 MHz or 133 MHz. It doubles the rate to 1.6 GBps and
2.1 GBps by transferring data on both the rising and falling edges of the clock.
DDR SDRAM uses additional power and ground lines and requires 184-pin
2.5V unbuffered DIMM module rather than the 168-pin 3.3V unbuffered
DIMMs used by SDRAM.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the mainboard. Handle the modules only by
their edges. Do not touch the components or metal parts. Always wear
a grounding strap when you handle the modules.
Installation Procedure
You must install at least one memory
module in order to use the main-
board.
Note: You cannot use DDR
SDRAM and SDRAM
simultaneously.
14

Refer to the following to install the memory modules.
1. Push the latches on each side of the DIMM slot down.
2. Align the memory module with the slot. The DIMM slots are keyed with
notches and the DIMMs are keyed with cutouts so that they can only be
installed correctly.
3. Check that the cutouts on the DIMM module edge connector match the
notches in the DIMM slot:

4. Install the DIMM module into the slot and press it firmly down until it
seats correctly. The slot latches are levered upwards and latch on to the
edges of the DIMM.
5. Install any remaining DIMM modules.
Installing a Hard Disk Drive/CD-ROM
This section describes how to install IDE devices such as a hard disk drive
and a CD-ROM drive.
About IDE Devices
Your mainboard has a primary and secondary IDE channel interface (IDE1 and
IDE2). An IDE ribbon cable supporting two IDE devices is bundled with the main-
board.
If you want to install more than two IDE devices, get a second IDE cable and
you can add two more devices to the secondary IDE channel.
IDE devices have jumpers or switches that are used to set the IDE device as
MASTER or SLAVE. Refer to the IDE device user’s manual. When installing two
IDE devices on one cable, ensure that one device is set to MASTER and the
other device is set to SLAVE. The documentation of your IDE device explains
how to do this.
15

About UltraDMA
This mainboard supports UltraDMA 66/100. UDMA is a technology that accel-
erates the performance of devices in the IDE channel. To maximize
performance, install IDE devices that support UDMA and use 80-pin IDE ca-
bles that support UDMA 66/100.
Installing a Hard Disk Drive
1. Install the hard disk drive into the drive cage in your system case.
2. Plug the IDE cable into IDE1
(A):
Note: Ribbon cable connectors
are usually keyed so that they can
only be installed correctly on the
device connector. If the connector
is not keyed, make sure that you
match the pin-1 side of the cable
connector with the pin-1 side of the
device connector. Each connector
has the pin-1 side clearly marked.
The pin-1 side of each ribbon ca-
ble is always marked with a
colored stripe on the cable.
3. Plug an IDE cable connector into the hard disk drive IDE connector (B). It
doesn't matter which connector on the cable you use.
4. Plug a power cable from the case power supply into the power connector on
the hard disk drive (C).
When you first start up your system, the BIOS should automatically detect
your hard disk drive. If it doesn’t, enter the Setup Utility and use the IDE Hard
Disk Auto Detect feature to configure the hard disk drive that you have in-
stalled.
Installing a CD-ROM/DVD Drive
1. Install the CD-ROM/DVD drive into the drive cage in your system case.
2. Plug the IDE cable into IDE1
(A). If you have already installed
an HDD, use the other connec-
tor on the IDE cable.
Note: Ribbon cable connectors are
usually keyed so that they can only
be installed correctly on the device
connector. If the connector is not
keyed, make sure that you match the
pin-1 side of the cable connector with
the pin-1 side of the device connec-
tor. Each connector has the pin-1
side clearly marked. The pin-1 side of
each ribbon cable is always marked
with a colored stripe on the cable.
3. Plug an IDE cable connector into the CD-ROM/DVD drive IDE connector (B). It
doesn't matter which connector on the cable you use.
